Here are a few system examples. Feel free to discuss or ask further questions, or submit your own beginner layouts for newbies.

Starter System 1
“This system assumes you have no other EuroRack modular gear or oscillator sources. The inclusion of an oscillator like Prismatic Ray really brings shapes and video to life. Staircase is the fastest way to create patterns and visual complexity. The ability to patch a ramp output from Visual Cortex into Staircase and use Prismatic Ray as a primary modulation source makes this a complex, fun and low cost way to step into LZX.” – Sam Newell

Starter System 2
“The most minimal configuration I could recommend, this system assumes you are expanding an existing EuroRack modular synthesizer which includes oscillators and other modulation sources. Bridge provides a scaling interface between your video and audio modules. Bridge also allows you to fade and mix ramps from Visual Cortex, which can then be processed by Staircase. With the Visual Cortex Colorizer & Compositor you can create many interesting patches from a very small system.” – Sam Newell

Basic System 1
“Building off of the Starter System 1, this layout introduces Shapechanger and Color Chords. The addition of Shapechanger instantly takes you out of solely making patterns and into the ability to generate complex and stunning shapes which can be mixed with patterns using Color Chords. Color Chords lets you dive deeper into the amazing analog color mixing capabilities that the LZX system provides, and gives you multiple layers to play with. This is important because of the vast amounts of possibilities within the Shapechanger + Staircase combination. Patching RGB out respectively into A or B on the Visual Cortex Compositor allows you to fine tune and filter through colors producing stunning combinations.” – Sam Newell

Hello everyone, i wonder if anyone would be so kind as to chime in with some words for the leyman!
I am entirely ignorant about video synthesis, but it’s always fascinated me and I have some questions if anyone cares to answer, please?

When i was a kid in the 70’s I saw what i think was an EMS Spectre/Spectron Video Synth.
The spec of this is:-

I don’t know anything about the EMS device you mentioned, but as to the different LZX lines, I think I can give my interpretation…

Cadet - DIY, the basic building blocks of analog video synthesis/processing, great for learning or as companion modules to other more complex modules

Castle - DIY, some basic building blocks for digital synthesis/processing (or in other terms, this series is about making and processing video using the CD4000-series logic chips), also good for learning or as companions to more complex modules

Orion - (presumably, since they’re not out yet) excellent feature-packed digital video modules (somewhat based on features found on classic digital video mixers, I think?)

That’s just how I differentiate the series in my mind. Lars and others probably have other ways of describing them. My Castle description should probably be better… Just calling it “digital video synthesis/processing” might be technically true in a way, but it’s not what one usually thinks of as digital video. Digital video usually involves things like bitstreams and color depth and frames and compression and many other things like that, but with Castle, it’s all very open and any part can take analog signals in or use the digital outputs as analog outputs, so a lot of the more strict concepts of typical digital video don’t really apply. That’s why I mentioned the logic chip series, since that’s the best way I could think to describe it without using a somewhat loaded phrase like digital video.

The EMS Spectre/Spectron was an inspiration for me when I made my first videosynth – using CMOS logic ICs. Castle is very much informed from that perspective.
The logic functions in the Spectre can be achieved with Castle, mostly. They differ in implementation. Theres no delay or edge processing (yet?). But you can do some edge type stuff with Castle with some clever patching, or using the Sandin IP Differentiator.
The oscillators on the Spectre are very interesting, and there’s nothing like it yet in LZX territory. You could nudge the oscillators up or down in scroll speed, horizontally or vertically! Pretty complex thing, using PLLs, counters, tracking filters.
The shape generators were also pretty interesting. You had a lot of shape options to choose from, something like that would be awesome in LZX as well. Clone, anyone?
For the oscillators Prismatic Ray is probably your closest bet, but with a lot more functionality and flexibility than the Spectre oscs – excluding the lovely scroll functions. But you’ll have a lot more CV control and more waveshapes.
For shape stuff, you can use Visual Cortex’s ramp section, which has a few different shapes, though not as many combinations as the Spectre.
OH, that reminds me about the ramp generator in the Spectre. There was a variable frequency Ramp, which is how you could get some stuff like Sierpinski triangles. I cloned the ramp section a while ago many years ago.

TL;DR
Castle has: counters, gates and inverters, flip flops, a video comparator of sorts in the ADC.
You can use Prismatic Ray for the oscillators.
Visual Cortex will give you shapes and mixing.

I think something close to the Spectre is possible, though not every function will be present, it’ll certainly be similar.

With Expedition series we tried to thoroughly analyze analog image processors, audio synthesizers and classic video synthesizers on a circuit wise and functional level, expand on those ideas with our own, and put them within the context of a next generation video instrument.

With Orion series, the approach is the same, it’s just that we’re focusing on a different category of device (and implied era of the 80s and 90s). So that encompasses everything from early DVE units like the Ampex ADO, dedicated video computers like Quantel Paintbox or the Amiga Video Toaster, hybrid devices like the Fairlight CVI, and also just early computer graphics and computer game consoles/devices as well.

So Expedition is a shot at what analog video could have been if it had progressed from the 70’s and into the 80’s without a digital video revolution transforming the market.

And Expedition series is a shot at what digital video (with analog interfacing) could have been if it had progressed into the late 90’s without a software video revolution transforming the market.

In both cases, they’re conscious experiments in retro-futuristic possibilities.

You have an exciting journey ahead. You can add just about anything to Memory Palace and get exciting results. Here is a powerful complete system with Memory Palace. You can add any of these modules as the next step after Memory Palace.

Memory Palace only has LZX patchable video inputs, you cannot connect an external video source to MP directly. You would have to use Visual Cortex, TBC2, Cadet III or Vidiot to decode it first – each of these has different capabilities. In addition to supporting several input formats, TBC2 will let you bring two different sources into the system and share sync between them and other video synth modules – currently you need some out-of-rack time base corrector for this.
